== Bottom and Top loop structure in ggH and ggA == 

Authors: Diogo Buarque Franzosi and Cen Zhang

== Description == 

This model allows the user to compute (pseudo-)scalar production through loop-induced gluon fusion at LO, in any decay channel, with interference with tree-level background. It takes into account the full top and bottom quarks loops. After loading the model with 

import model Higgs_Effective_Couplings_FormFact

You can run, e.g.:

p p > h > t t~ (signal scalar) 
p p > h1 > t t~ (signal pseudo-scalar)
p p > t t~ HIG=1 / h1 (signal scalar + background and interference)
